we own a 2002 beaver santiam with a rr8r chassis. after running this coach down the road for 5 yrs we love the handling but the ride has always been pretty rough. especially on those small holes, strips in the road, most of you know what i mean! well koni has been advertising their koni fsd model shocks helping to eliminate this problem. i had them installed on the front only to try them. unbeleivable! they have totally changed the ride quality to great! now i can't wait to install them on the rear.
